PORTABIQE SELF CLEANING BUILDTNG MATERIAL CUTTER Filed Aug. 18, 1941 Patented Dec. 9, 1941 s'ra'r PORTABLE SELF-CLEANING BUILDING MATERIAL CUTTER 1 Claim.

My invention relates to improvements in a portable building material cutter adapted for better and more convenient and economical use, at the place of erection, for cutting compositions required for insulations and roofings and outer sidings, providing a less complex means for said cutters self-cleaning from tar like adhesions generally contained in such materials.

The objects of my invention are to provide a portable self cleaning building material cutter which is less costly and more durable and beneficial for use and, to these ends with other objects in view, this invention consists of the devices and construction hereinafter described and illustrated in the accompanying drawing, in Which The figure is a perspective view of my portable self cleaning building material cutter improvement, shown with one sectional portion thereof broken, and wherein like reference numerals indicate like parts throughout the drawing.

Numerals I and I refer to the building material cutters table surface, preferably formed by joining two like 2 and 2 angle iron sections with ordinary bolts 4 and 4, having a slot 3 provided therein, by preferably interpositioning a strap iron compression lever holding post 5 at one end thereof, through which the cutter blade I 9 can become submerged. Numerals 6 and 6 refer to like sleeve position holding furls, at each side of said 5 posts base, through which bolt 4 is secured, and numerals l, I, refer to ordinary strap iron table supporting legs, which are readily secured at 8, 8, to any portable object.

Numerals 9 and 9 refer to a broken surface, in one of said angle iron sections 2, showing the self cleaner depository l0, containing preferably gasoline or some other like solvent, which is secured to the sides and bases of said angle irons 2 and 2, as referred to by numeral II, and said cleaner depository has a fibrous covering I2 provided with a slit l3 therein, through which aforesaid cutter blad I9 is required to submerge into I the cleaner depository solvent.

Numeral i l refers to a compression lever, preferably formed by joining two unequal lengths of strap iron l5 and I6, with ordinary bolt H, and whereby the longer section provides the handle i8, and which is operatively bolted to aforesaid holding post 5, as shown by numeral 24. Numeral I9 refers to the cutter blade, which is either clamped between, or secured to, aforesaid compression lever strap irons l5 and 16, as shown by numerals 2| and 22. The cutter blade i9 is reinforced at its rear edge by supporting bar 23 and the blades front cutting edge is referred to by numeral 20. Numeral 25 refers to a double retention guard, bolted to the sides of aforesaid holding post 5 as shown by numeral 26, under which the cut material is made to pass.

Aforesaid composition material is shoved forward on and along aforesaid cutters table surface, i and l, toward and over fibrous covering slit l 3 and thereupon compression lever I4 is lowered and cutter blade l9 becomes submerged into cleaner depository 10's solvent and when said compression lever M is raised, to its initial position, the cutter blade becomes wiped clean by the under sides of slit l3s provided fibrous covering.

What I claim and desire to secure by Letters Patent is:

A portable cutting device for roofing sheet which contains tar as one of its constituents, the combination of a table, a post at one end thereof, a lever pivoted to said post, a cutting blade fastened at a point along the lever, a gasoline container mounted beneath said table, a fibrous covering over the open end of said container, the table having a slot communicating with the open end of said gasoline container through which said cutting blade passes into the gasoline container when performing a cutting operation, whereby the cutting blade is cleaned of tar and wiped, and a guard for the material worked upon fastened to said post.
